HC, Thanks for all the advice. I will try out."For the shins: tap the shin bone near the knee and near the ankle. "
Shin splints: can you be a bit clearer. what I should tap with? When should I tap it?

My race is in 4 weeks. Will I have enough time to train if I take 2 weeks off? I am kind of worry about that. Is biking a good alternative?
Thanks, Mai
